Just a status update ...
I'm working on the pure time64 and 64bit off_t syscalls support, it almost worked (tested on rv32/64, arm32/64), thanks very much for your suggestions.
It includes:
Based on linux/types.h and
- Use 64bit off_t
- Use 64bit time_t
- the new std.h looks like this
typedef uint32_t __kernel_dev_t; typedef __kernel_dev_t dev_t; typedef __kernel_ulong_t ino_t; typedef __kernel_mode_t mode_t; typedef __kernel_pid_t pid_t; typedef __kernel_uid32_t uid_t; typedef __kernel_gid32_t gid_t; typedef __kernel_loff_t off_t; typedef __kernel_time64_t time_t; typedef uint32_t nlink_t; typedef uint64_t blksize_t; typedef uint64_t blkcnt_t;
Use __kernel_timespec as timespec
Use 64bit time_t based struct timeval
- Disable gettimeofday syscall completely for 32bit platforms
- And disable the gettimeofday_bad1/2 test case too
When you say "disable", you mean "remap", right ? Or do you mean "break in 2023 code that was expected to break only in 2038 after the hardware supporting it no longer exists" ?
Thanks, Willy
